Chalamadad, I am not driving with a pulse motor system like RomeroUK presented.  I am driving the rotor with a VCR head motor on a regulated DC supply.  This is so I can change the RPM more easily by adjusting the input voltage/power.  Truth be told, I have not yet found any correlation between increased o/p power and RPM (yet), so the fact that I have easy RPM control might not be a requirement for a self runner.  More testing and time will tell... (I hope)

Hey Mond

Have you tried reverse diodes(freewheel diode) across your drive coils?   It will increase your rpm but not your input.  ;]


Just put the diode across the coil in a fashion that it wont conduct when the drive circuit is sending power to the coil.( cathode/silver bar on the +side of coil)  The diode will keep the coil on for a bit longer without drive input. This will give you more rpm.  ;]

Ive said this earlier but nobody listened. It works.

Well, as embarrassing as it looks, here are a couple pics.

Yes, I only have ~200 wraps of 24 AWG on single fi coils right now.

I went back to my notes and found a maximum UNLOADED reading of 16.77V across the dump cap while running 2231 RPM.  This dropped to 8.42V with 70.7 mAmps being drawn by a small bulb.  RPM also dropped to 1675 with the bulb load.

These readings were with just one coil pair.  Those were wired Tesla bi-fi and were as close to the rotor as I could get them without crashing.  So they were ~ 1/8 inch away from the rotor magnets.

I have not seen anything to indicate that bi-fi is better for gen coils in my testing.

M.   Nice looking rig.   Not ugly at all and thank you for sharing your data.

I do what I do because I can.

Thanks for the props.

Hey everyone. Really great work going on here. Sorry I don't participate in this thread much. It just moves so fast I'd have to hire someone to filter out what's relevant for me. 

Anyway, I'm attaching a few pics of where I'm at lately with my build.

And I have a question. Are there any new revisions to the RomeroUK PDF document v1.1 that I have shown at my web site http://www.alt-nrg.org/ ? Please advise so I can keep my site as up to date as possible.

Thank you all.

Call it a "neutral zone" if you wish, but it should not be called a "Bloch Wall". This only perpetuates the misnomer, and facilitates a misunderstanding of the magnetic field in and around a magnet.

After re reading your post, I have decided I agree with your stance on definitions, and have edited my site. Actually, it gave me a chance to clarify on page 4 and 5, that the neutral and transition zones only exist when a magnet is interacting with an external element.

Thanks for being a stickler for technicalities.
